Tach/Fuel Adapter

(No reviews yet) Write a Review


Use this Tach Adapter if you are using the magnetic pickup input (green and violet wires) to trigger your MSD Ignition. It will correct the operation of most voltage-triggered tachometers that do not work directly off the tach output terminal of the MSD control. This Adapter should also be used on current-triggered tachs (hooked in series with the ignition switch).
